Open brace unexpectedly wrapped in `guard` statement

[calda]

When testing develop on our codebase, I encountered one issue where the open brace of a closure in a guard statement would be wrapped unexpectedly. Here's a test case that fails on develop (which I'd expect to pass):

func testOpenBraceAfterEqualsInGuardNotWrapped() {
    let input = """
    guard
        let foo = foo,
        let bar: String = {
            nil
        }()
    else { return }
    """

    let options = FormatOptions(
        wrapArguments: .beforeFirst,
        closingParenOnSameLine: true
    )
    testFormatting(for: input, rules: [FormatRules.wrapMultilineStatementBraces, FormatRules.wrap],
                   options: options, exclude: ["indent", "redundantClosure"])
}

here's a commit that includes that test case: https://github.com/calda/SwiftFormat/commit/8d121bfb378a84fed27f1423a6efae156a50a8b4
